This command sets actions to be taken after Extreme Loop Recognition Protocol (ELRP) on dynamic This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches.s detects a loop.
| dynamic-vlans | ELRP configuration options for dynamically created VLANs. |
| mvrp | Specifies that the command applies to dynamic VLANs created by Multiple VLAN Registration Protocol (MVRP) only. |
| netlogin | Specifies that the command applies to dynamic VLANs created by Network Login only. |
| vm-tracking | Specifies that the command applies to dynamic VLANs created by virtual machine MAC tracking only. |
| all | (Default) Specifies that the command applies to all types of dynamic VLANs. |
| interval | Specifies setting the time interval between successive ELRP polls. |
| sec | Sets the time interval in seconds between successive ELRP polls. Range is 1–600. Default = 1. |
| action | Action to be taken after ELRP poll result. |
| log | Print ELRP poll result to system log. |
| trap | Send SNMP trap. |
| log-and-trap | Print ELRP poll result to system log and send SNMP trap. |
| disable-port | Disable port where looped PDU was transmitted or received. |
| egress | Disable port where looped PDU was transmitted. |
| ingress | Disable port where looped PDU was received (default). |
| duration | Specifies setting the time period that the port is kept disabled before re-enabling. |
| seconds | Sets the time in seconds that the port is kept disabled before re-enabling. Range is 15–600. Default = 30. |
| permanent | Keep port disabled permanently. You must intervene to re-enable. |
| none | Removes any previously set actions. |
If the type of dynamic VLAN is not specified, the command applies to all types of dynamic VLANs.
If the time duration is not set for the period between ELRP polls, the default is one second.
If not specified, the port that the looped PDU was received on is disabled.
If not specified, the disabled port is kept disabled for 30 seconds before it is re-enabled.
The following example enables ELRP for all types of dynamic VLANs with a time interval between ELRP polls of 2 seconds:
configure elrp-client dynamic-vlans interval 2
The following example enables ELRP for MVRP VLANs with SNMP trap set when a loop is detected:
configure elrp-client dynamic-vlans mvrp action trap
The following example enables ELRP for all types of dynamic VLANs and disables the egress port where the loop is detected permanently:
configure elrp-client dynamic-vlans action disable-port egress permanent
The following example enables ELRP for VM-tracking VLANs and disables the ingress port where the loop is detected for 100 seconds:
configure elrp-client dynamic-vlans vm-tracking action disable-port ingress duration 100
